Abstract

          This work aimed to report on a case of a classical triad comprising progressive though painless visual loss, optic atrophy and optociliary shunt vessels from optic nerve sheath meningioma. The author conducted a case report of a 55-year-old female who presented with chronic visual loss. The patient’s symptoms and signs, radiographic findings and management were described. Eye examinations revealed mild proptosis, optic atrophy and optociliary shunt vessels in the left eye. Magnetic resonance imaging (MRI) of the brain revealed an enhancing mass around the intra-orbital and canalicular region of the left optic nerve, exhibiting intermediate signal on T1 weight and a slightly hyperintense signal on T2 weight. It measured about 1.4 x 3.6 x 1.1 cm. It is likely these are also optic nerve sheath meningioma. The patient received radiotherapy, though her symptoms did not improve.


          This patient had a classic triad of optic atrophy, visual loss, and optociliary shunt vessels. MRI findings are particularly useful for the diagnosis of tumors.
